The Agroindustrial System coffee after decades of state regulation has become a decentralized economic activity. This situation compelled most of the actors in the production chain to resort to self r egulatory systems offered by certification agencies, which have specific criteria and procedures. However the diversity criteria of the agencies do not offer resources able to ensure efficient management of the governance structure. There is a need to reduce the asymmetry of information, which is possible through the sharing of data compatible with the production tracking feature. This work is supported in this contextualized problem, based on Transaction Cost Theory and the use of qualitative and quantitative research methodologies. The first part of the work seeks to know the procedures required by leading regulatory agencies in Brazil, with perspective to emphasize the similarities and compatibilities between them, which was reached after analysis of standards and comparison of similarities. Next is registered the operation and the coffee traceability of the structure, in order to identify, through observation, documental and bibliographical analysis, the systems in place and traceable information in line with the recommendations of the coffee certification. Finally, he sought to create a labeling model that allows to generate and share information about the product from the field to the sale for consumption. The information obtained in the previous steps were the basis for data collection with the production chain agents through a structured questionnaire administered to 618 agents of the production chain, whose answers were treated by multivariate methods of statistical analysis. The results showed that actors in the chain are in favor of inclusion and sharing information related to rural production and economic and environmental data. This knowledge enabled develop a labeling model where the information sharing agents is an efficient mechanism to mitigate the governance problems identified.

Amazônia brasileira oferece um apreciável potencial de plantas com propriedades terapêuticas, embora a maioria seja pouco conhecida. Dessa forma, com o objetivo de verificar a potencialidade nutricional de ervas medicinais, determinou-se a concentração de Ca, Mg, Fe, Cu e Zn nas folhas e nos chás das espécies: Piper callosum Ruiz & Pav., Piperaceae, Mikania lindleyana DC., Asteraceae e Arrabidaea chica (Humb. & Bonpl.) B. Verl., Bignoniaceae. As amostras de plantas depois de terem sido processadas, foram submetidas a digestão e em seguida realizada as leituras dos metais em um espectrofotômetro de absorção atômica. Para o chá de Arrabidaea chica foram detectados teores de Ca (6955 a 20058 mg/L), Mg (2390 a 3094 mg/L) e Fe (40 a 61 mg/L). Para o chá de Mikania lindleyana além da presença de altos valores de Ca (17722 a 22336 mg/L), Mg (4531 a 9370 mg/L) e Fe (20 a 87 mg/L) foram encontrados de 7 a 16 mg/L de Cu e 9 a 41 mg/L de Zn. O chá do Piper callosum apresentou em média 2036 a 4344 mg/L de Ca, 618 a 4023 mg/L de Mg e 39 a 60 mg/L de Fe. Comparando-se os resultados dos minerais com os valores recomendados pela Organização Mundial da Saúde, conclui-se que os metais presentes nos chás das plantas poderiam contribuir na complementação das dietas alimentares das pessoas que as utilizam.
